Question

我想检测拨出呼叫何时开始和结束，并希望在呼叫开始时启动服务，并在呼叫结束时结束服务。

这是我从另一个问题得到的代码，但不知道在哪里放置启动和停止活动以使其工作。

public class CallListener {

private CallStateListener callStateListener = null;
private OutgoingReceiver outgoingReceiver = null;

public CallListener(Context context) {
this.context = context;

callStateListener = new CallStateListener();
outgoingReceiver = new OutgoingReceiver();
}

private class CallStateListener extends PhoneStateListener {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
  switch (state) {
  case TelephonyManager.CALL_STATE_IDLE:
    doSomething1();
    break;
  case TelephonyManager.CALL_STATE_OFFHOOK:
    doSomething2();
    break;
  case TelephonyManager.CALL_STATE_RINGING:
    doSomething3();
    break;
  }
  }
  }

  public class OutgoingReceiver extends BroadcastReceiver {
  @Override
  public void onReceive(Context context, Intent intent) {
     doSomething4();
 }
 }

 public void start() {
telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(callStateListener, PhoneStateListener.LISTEN_CALL_STATE);

IntentFilter intentFilter = new IntentFilter(Intent.ACTION_NEW_OUTGOING_CALL);
context.registerReceiver(outgoingReceiver, intentFilter);
 }

public void stop() {
telephonyManager = (TelephonyManager)       context.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(callStateListener, PhoneStateListener.LISTEN_NONE);

context.unregisterReceiver(outgoingReceiver);
}}

这是添加服务以使其工作：

public class MyService extends Service {

private CallListener call = null;

public MyService() {
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
call = new CallListener(getApplicationContext());
call.start();
return(START_STICKY);
}

@Override
public void onDestroy() {
call.stop();
call.onDestroy();
}

@Override
public IBinder onBind(Intent intent) {
return null;
}
}

非常感谢您的帮助，我可能知道这很容易，但我只是不知道。

谢谢，祝你有个美好的一天.. !! ：）

我已经搜索过如何检测铃声/空闲/等等呼叫事件......没有成功:( 不幸的是，Android目前还没有解决方案......

在上一个问题/摘要帖子中对此进行了详细解释：
